Mastro valvola LEM - lysergic emotions module 多功能 调制延时
LEM是一个multi-head delay 多源调制延时踏板，有8种效果模式，旨在激发梦幻和实验环境。在使用这种效果时，很容易遇到独特的、催眠的或意想不到的声音环境，如闪烁重复、反向延迟、多头调制、音高偏移、低保真声音等等。
REVERSE - 标准反向延时 /带有vibrato level -震荡音量参数
LFO rev - 低频滤波震荡反向延时 /带有vibrato level -震荡音量参数 /octave up pitch高八度移调
LFO rev - 低频滤波震荡反向延时 /4级滤波参数
Multi - 多功能磁带延时 /WOW（磁带速度功能级别）
Low shim - 低八度 闪烁音色 /bit crusher resolution 比特化发声处理 /octave down pitch 低八度移调
Lo-fi amb - LO-FI低保真空间环境延迟/混响 /bit crusher resolution 比特化发声处理 /octave up pitch高八度移调
Multi - 多头延迟-每次延时为正向或反向
Shim - 闪烁音色延时 /bit crusher resolution 比特化发声处理 /octave up pitch 高八度移调

The LEM is a multi-head delay pedal with 8 effect modes, designed to inspire dreamy and experimental ambiances. While playing with this effect, it's easy to run into unique, hypnotic or unexpected sound environments like shimmering repeats, reverse delays, multi-head modulations, pitch shifting, lo-fi sounds and more.
8 ambiance types
True bypass with Timed Bypass System (TBS), to manage the trails and the bypass switching style
Separate Dry and Wet controls
CTRL input: exp/cv or remote switch
Wet sets the level of the wet signal.
Dry sets the level of the dry signal.
Delay sets the delay time.
Special each mode has a special effect, the
Special knob controls it.
Filter sets the frequency of the analog filter
applied to the wet signal. The control is flat in
its central position and allows you to emphasize
the low frequencies going left, or the
medium-high frequencies going right.
Feedback sets the number of repeats.
(SHIFT) some of the controls have more than
one function. The main function is indicated in
white text. Hold the SHIFT button to have access
to the alternate function (orange text).
Exp / cv sets the parameter that can be
managed with the Exp pedal or Control Voltage.
Mode switches between 8 types of delay modes.
Tap sets the delay time (Tap Tempo).
Bypass (preset) bypasses or engagees the effect.
Holding SHIFT while pressing it will access the
next preset. (see page 2)
Trails when the effect is engaged, hold the
SHIFT button and bypass footswitch for 3 seconds
to change the bypass mode to Trails Mode (this
will make the repeats persist after the effect is
turned off). When the Trails led is lit the Trails
mode is engaged.
SAVING A PRESENT
When you have created an effect you like, you can save it in one of the 4 presets available.
- when the effect is engaged, just hold the (PRESET) and SHIFT button for 1 second. The led will start
- choose the colour of the preset you wish to save the effect by pressing the (PRESET) and SHIFT
button (the first preset that will be available is the RED one, followed by GREEN, BLUE and then
YELLOW; by pressing the PRESET button again after the YELLOW preset, you will exit the saving
mode and go back to the previous mode);
- hold the (PRESET) and SHIFT button for 1 second on the chosen colour. The led will stop blinking.
When a PRESET is saved, the "now playing" parameters will be saved, including the EXP/CV control
and the chosen TRAILS management mode.
When one of the presets is in use, modifying the position of one of the controls will update the relative
parameter based on the new position and the led will start blinking slowly. To save the modified
presets just follow the steps below.
Saving a preset from Manual mode, all parameters will be saved based on the position of the controls.
Saving from the Preset mode, the parameters relative to the current preset will be saved, updating them
based on the changes made to the controls.
CTRL (control) input
The CTRL input supports 2 different methods of remotely controlling the effect. The LEM CTRL input
has an automatic recognition function of the jack that is inserted. When a stereo (TRS) jack is inserted
the pedal is set in the EXP / CV mode. Instead when a mono (TS) jack is inserted the pedal is set in the
Remote Switch mode.
1. Expression pedal or CV (TRS jack). Parameter selectable via toggle switch on the front panel.
- Expression pedal: the LEM supports most types of expression pedals for performance control.
Just about any expression pedal that uses a TRS cable should work. Tip goes to wiper.
- Control Voltage (CV) 0-5V range on Tip. The Ring should be left floating in this case.
2. Remote: TAP switch, PRESET switch or BYPASS switch.
- Plug a mono jack into the CTRL port.
- Hold the SHIFT button and the REMOTE footswitch for 3 seconds to switch between the 3
configurations. The first configuration that will be available is the TAP one, followed by PRESET and
BYPASS. The “preset” LED will blink white to indicate that the configuration has been changed and
saved. The configuration is remembered when the device is unplugged or power is turned off.
